I’m sorry to hear you are experiencing this. I tried to replicate this on my local installation and was not able to replicate the issue that you are reporting.
Can you update your Ninja Forms plugins to their latest versions and let me know if you continue to have the same issues?
Can you then try temporarily deactivating all your plugins that are not Ninja Forms add-ons and switching to a default WordPress theme like Twenty Sixteen. If this solves your issue, then the problem was caused by an issue in one of those plugins or your theme. Reactivate them one at a time until the issue returns to determine which plugin is causing the conflict.
If you do not have a development environment for your site (this is best practice and highly recommended),you can use the Health Check plugin (https://wordpress.org/plugins/health-check/) to temporarily disable plugins and your theme for a single user session, instead of all users using your site.
If you continue to have issues, can you contact our official support channel. http://ninjaforms.com/contact
Hi there,
thanks for your reply… but can’t understand why you marked this ticket as “Resolved” when it was actually NOT. I did as you suggested, but even with no other plugin or add-on active and using a default WP theme, the issue persists. I ended up exporting and importing the form I wanted to duplicate… but, again, the issue still persists. Just to let you know.
